I ride primarily on the interstate back and forth to work daily. Probably about 20 miles. With the rpms constantly roun 9-11, which is helping the fuel efficiency much. Does anyone have any recommendations that might make the bike better at speed 70-80 mph.
A 15 tooth front and a 43 tooth rear sprocket offers the best balance of acceleration and top speed provided you are maxing out rpms in every gear. Your rpm speed will decrease about 750 rpm in any given gear, but you will see an increase in top speed.
Easiest thing to do is just a larger rear sprocket. Takes about 20 minutes to swap out.
Next time you need a new tire, you could use a slightly bigger one.
took much less time for me to do the front. I'd assume both can be changed very quickly. The rear tire comes off so easily and if you know what you're doing with the adjustment and chain tension, it should be so easy
